Try pin sausage lentil soup with spinach later!

A few years ago, when my brother Rand happened to be in Utah for my father’s 85th birthday party, I made a double lentil, sausage, brown rice, and spinach soup in my slow cooker. Sometimes I always like to try my culinary experiments and loved the soup so much that when I got home I asked if I could get the recipe before posting it on my blog. I think the version he still enjoys making.

Now I adapted that old soup recipe to this new one. Spinach sausage lentil soupuse the link above to view the original recipe and you’ll probably understand why I wanted to make a low carb soup that tasted the same! Also, since I made this a stovetop soup, I used more chicken broth than the original soup and these changes reduced the carbs to 7 net carbs per serving!

This is a relatively long-cooking soup for a stovetop recipe, but I recommend simmering the soup over low heat so the house smells good! I love making soup in a crockpot! If so, you can also adapt this new low-carb recipe to make it in your slow cooker using the original slow cooker instructions linked above.

Spinach Sausage What sausage did you use in your lentil soup?

Some turkey and chicken sausages have sugar, so be careful if you don’t want the extra carbs.

What if you don’t have balsamic vinegar?

If you don’t have balsamic vinegar, you can use red wine vinegar instead. If you want to use a lot, you may use a little less while tasting.

How could this soup be even lower in carbs?

If you want an even lower-carb version of the soup, switch carrots for celery, lentils for another cauliflower rice, and balsamic vinegar for red wine vinegar.

Low Carb / Low Glycemic / South Beach Diet Suggestions:
By switching the rice to cauliflower rice, using more sausage, and using more broth, this sausage and spinach lentil soup turned into a soup with just 7 net carbs per serving. When made with low-fat chicken or turkey sausage, this is also great for Phase 2 or 3 of the original South Beach Diet (or any phase if you replace carrots with more celery).
